The primary task of protecting consumer rights is to prevent products that consumers are dissatisfied with and products that may cause harm from entering the hands of consumers; to compensate for products that cause harm to consumers' health or life or property losses. Gas appliances are special products. Ensuring the safety of gas appliances is not only the responsibility of manufacturers and sellers, but also the use of gas appliances, gas quality and installation of gas appliances are also important conditions for ensuring the safety of gas appliances. Consumers and common sense of gas appliances are also important aspects. To prevent gas appliances from harming consumers, national laws, regulations and technical measures are mainly used to provide guarantees. The following measures are mainly used to prevent dangerous gas appliances from flowing into consumers through laws, regulations and technical means: a) Formulate gas appliance safety performance regulations and technical requirements; h) Follow safety requirements in design, production and sales: Confirm the responsibilities of gas appliance manufacturers and sellers: Carry out safety supervision of gas appliances, including monitoring of gas appliance quality and installation; Prohibit the import of potentially dangerous gas appliances; Inform consumers of which gas appliances are unsafe: Remove any unsafe gas appliances from the market and keep them away from consumers. g)
After China joined the WTO, since the country's laws, regulations and product standards have not been fully aligned with the international market, in order to prevent the different levels of protection for gas appliances provided by the laws and standards of different countries, resulting in trade barriers and unequal competition, this standard is specially formulated to regulate market behavior. Together with GB16914, this standard has established specific behavioral norms for domestic and foreign producers and sellers. 1 Scope
